SPECIFICATION forming pere of Lettere Patent Nefoaerl, dated Mey 2, 1899. Application led December 19, 1898. Serial No. 699,663. (No model.)

To @ZZ whom, it may concern:

Be it known that I, JAMES H. NoRTHRoP, of l-Iopedale, county of Worcester, State of Massachusetts, have invented an Improvement in Looms, ot' which the following description, in connection with the accompanying drawings, is a specication, likeletters and figures on the drawings representing like parts.

This invention relates more particularly to that class of looms provided with automatic iilling-supplying mechanism, including an intermittingly-operated filling-feeder for supporting a series of filling-carriers bytheir heads and tips, the feeder holding a llingcarrier in such position When the loom is running properly as to be directly in the path of the pusher or transferrer adapted to automatically transfer such.iilling-carrier into the shuttle upon failure of the filling or upon exhaustion of the latter to a predetermined extent, such a loom being shown in United States Patent No. 529,940.

My present invention has for one of its 0bjects the production of novel means for engaging the ejected fillingcarrier as it is pushed ont of the shuttle-box by the incoming fresh filling-carrier, the catcher which receives the ejected'lling-carrier being thereafter moved away from the shuttle-box to a suitable dischargepoint, whereat the filling-carrier is positively expelled from the catcher.

In United States Patent No. 563,611, dated July 7, 1896, a loom isshown provided with a catcher for an ejected filling-carrier, said catcher comprising pivotally-connected jaws which are opened at the proper time to per-` mit the tillingcarrier to drop out and mounted upon the loom-frame, whereas in my present invention the catcher is mounted upon the lay and movable laterally thereto at the proper time to discharge the iillingcarrier caught by it, the latter being made operativev by or through the action of receiving the filling-carrier ejected from the shuttle-box.

' Certain other features of my invention, to be hereinafterdescribed and clai med, concern the peculiar construction of thetransferrer for the filling-carrier, whereby the lling-carrier is more completely controlled during its transfer from its filling-feeder to the shuttle.

Figure 1, in front elevation, represents a suflicientportion of a loom provided with automatic filling-supplying mechanism to be understood and with my present invention applied thereto, the iilling-supplying mechanism being substantially as shown in United States Patent No. 529,940 referred to. Fig. 2 is a transverse sectional view thereof ou the irregular line x, Fig. 1, looking toward the left, the lay being shown back and with the various partsin normal position. Fig. 2ct is an enlarged perspective detail of a portion of the transferrer to be described. Figs. 3 and 4 are sectional views taken on the line a2 Fig. 1, the lay being shown as fully forward in Fig. 3 and showing the transferrer as hav,- ing just inserted a fresh filling-carrier into the shuttle, while theejected filling-carrier is engaged by the catcher, the latter being shown in Fig. 4in discharging position, the' transferrer having returned to its normal position and the lay moved back. Figs. 5 and 6 are enlarged opposite side views of the catcher detached, and Fig. 7 is a perspective View of the expeller and dog connected therewith. y I

The loom-frame A, the breast-beam A40, lay A3, having the bottom of one of its shuttleboxes cut away below the self-threading shuttle S, the filling-feeder comprising connected rotatable plates suitably shaped to receive the ends of the filling-carriers b, the weftthread-supporting plate h', the stud f, the transferrer or pusher f', mounted thereon vand having the forked depending end f*s and a lateral projection 21, and the shaft d', adapted to be rotated by the movement of the weft-fork in the absence of the filling, are and may be all as represented in said Patent No. 529,940, wherein like letters are used to designate the same parts, which are operated in practice substantially as provided for in said patent. e

. The shuttle feeler or detector k2, connected at its upper end to one of the arms c2 of a sleeve or hub c, rotatably mounted on the stud f, the longitudinally-slotted link d, jointed at its lower end to an arm d2, fast onV the rock-shaft- CZ' and connected at its upper ICO `end to a second arm on the sleeve or hub c,

(not shown,) and the downturned and laterally-bent arm c3, provided with a slotted .iinger n, the rocker-stud m, provided with a disklike head and mounted in the forked end f3 of the transferrer, the arm m2, fast 'on said stud and carrying a notched dog mx, the lateral projection or lug m4 on the arm m2, with which the finger n at' times cooperates, the spring s to normally retain the dog in inoperative position, and the bunter C2 on the lay to engage said dog and operate the transferrer when a filling-carrier is to be transferred from the iilling-feeder to the shuttle by the transferrer f', provided the shuttle is properly boxed, may be and are all as represented in United States Patent No. 568,455, dated September 29, 1896.-

y The finger 21, laterally extended from the outer end of the transferrer j", is enlarged and downturned at its outer end, as at 22, and slotted, as at 23, Fig. 1, to receive therein the upturned tongue e30 of a cushion, (shown separately in Fig.- 2,) made preferably of rubber or other suitable yielding material,

-said cushion having depending and downwardly-divergent cheeks c?" to leave a deep V-shaped notch or recess C32 between them, with its open end downward, the cheeks being extended laterally beyond the tongue and upturned at each side thereof, as at 033, to embrace and practically cover the edges and `the correspondingly-notched lower portion of the depending end 22 of the finger.

The main portion f of. the transferrer engages, as is usual, the head end of the fillingcarrier, while the tip end of the latter enters i the-V-shaped notch C32 of the cushion. This construction of the tip-engaging portion of the transferrer not only prevents any side motion of the filling-carrier during its transfer, but positively controls it during such movement.

When a filling-carrier is ejected from the shuttle, its tip will sometimes rise diagonally .and-ily out of the shuttle between the wall of the latter and the tip-engaging portion of the transfert-er, jamming the parts so that the fresh filling-carrier cannot be properly inserted in its place. By the construction herein shown, however, the tip of the fresh fillingcarrier enters and is engaged by the sides of the deep V-shaped notch near the bottom thereof before the said filling-carrier fully enters the shuttle, while the extremities of the cushion or part in which the notch is' made enter the shuttle between its side walls and interpose an effective obstruction to any improper lifting movement of the tip of the spent filling-carrier, so that the latter cannot possibly Hy up sidewise and jam against the shuttle-wall when ejected. Should the tip rise, it will only enter between the sides of the'notch, where it can do no harm.

, The cushion is so made that its laterally-projecting portions act to incase the metal of the end 22 with rubber or other yielding material at all points which might engage either the filling-carrier, the thread, or the shuttle, so there is no possibility whatever of the illingthread being caught between the cushion ,and the part of the finger to which it is attached.- Referring to Fig. 4,the dotted line 5 is shown as drawn through the centers of the stud f and the nger 21, while the line 6 is drawn centrally through the downturned end 22 of the finger and bisecting its notch to more clearly show that the tip-engaging portion is set at an obtuse angle with the main portion f of the transferrer. The utility of this construction will be observed by reference to Fig. 3,wherein the tip-engaging portion 22 is shown in the shuttle, the angle at which it is set relative to the transferrer f permitting the tip-engaging portion to enter and recede from the shuttle without touching the sides of the latter, thus effecting a more accurate and freek movement of the transferrer when a filling-carrier is moved from the filling-feeder to the shuttle. A bracket g, secured to and depending from the lay adjacent the slotted shuttle-box, has pivotally mounted upon it on a stud g the catcher for the ejected iillingcarrier, said catcher being shown separately in Figs. 5 and 6 as an upturned bent arm H and having attached to its upper end, as by a bolt 1.2, two upturned preferably resilient or spring-jaws h h' of such length that when the catcher is in normalposition the rearmost jaw 7i. will partly enter the slot 35 in the bottom of the shuttle-box, the tips of the jaws being slightly bent in toward each other.

The stud g',which is rigidly secured to the catcher and rotatably mounted in the bracket g', has attached to it'one end of a strong spring 153, Fig. 1, the other end of the spring being secured to the bracket, the normal tendency of the spring holding the catcher in the position shown in Figs. 1 and 2, with the jaws h h below the head `end of the illing-carier when' the shuttle is in the shuttle-box.

The arm H is longitudinally slotted below the jaws at 7L? to receive the lateral projection i on an L-shaped casting, (shown separately in Fig. 7,) comprising an expeller and a dog,

ICO

IOS

IIO

which, as will be described, controls the l movement of the catcher into discharging position to positively expel the filling-carrier from the catcher. K

The upper arm 712 of the casting forms the `eXpeller proper, and it is extended at right angles to the catcher H between the jaws h h and is movable up and down between them, a detent h3, shown as a thin metal plate attached tothe side of the catcher, entering a longitudinal groove sin the projection t', preventing disengagement of the eXpeller from vthe catcher, while permitting its movement relative thereto.

A spring s4 is interposed between the under side of the expeller and the upper end of the catcher to normally-retain the expeller in the position shown in Figs. 2 and. 5, the expeller at such time being so near the opening between the jaws that it will be engaged and `retracted or pushed in. by the entrance of a lling-carrier ejected from the shuttle-box.

The main portion of the casting at right angles to the eXpeller forms a dog t4, as it may be termed, having near its upper end a shoulder or stop and a cam-surface i, extended from the shoulder to the lower end of the dog, while at its opposite. side and at its lower end the dog is provided with a second shoulder i7.

The catcher is located at the inner side of the bracket g, as best shown in Fig. l, and the dog is on the inner face of the catcher,

with its cam-face i turned toward the back Y of the loom and. held normallyby the spring s4 above an actuator (shown as a bunter HX) attached to the loom side A, the said bunter or actuator being preferably rounded on its under side, as at 3S.

Referring now to Fig. 3, where the lay is shown as forward and with vthe bunter C2 in engagement with the dog mx, the transferrer having been thereby actuated in well-known lnanner to transfer a fresh filling-carrier b from the filling-feeder into the shuttle S then in the shuttle-box, having a slotted bottom 35, the entrance of the fresh filling-carrier into the shuttle has operated to eject the spent filling-carrier 530 from the shuttle and shuttle-box and into or between the jaws of the catcher, the ejected filling-carrier depressing the expeller t2, and thereby the dog 4, with the lower end of the cam-surface i below and in the path of the actuator HX, as clearly shown in Fig. 3, the center of the ejected filling-carrier being below the tips of the jaws 7L h.

thereby move the catcher relativelyto the lay, swinging it on its fulcrum g into discharging position (shown in Fig. 4) just before the lay completes its backward movement, the lling-carrier still being held between the jaws of the catcher. As the lay completes its backward movement, however, the actuator will engage the shoulder i5 of the dog and will positively move the eXpeller t2 toward the outer ends of the jaws, carrying with it the filling-carrier Z930, until its center is past the tips of the jaws, whereupon the latter will tend to spring toward each other to thereby snap the filling-carrier from the catcher and preferably into a sui-table box or receptacle B40. (See dotted lines,` Figs. l and 2.) The catcher having thus fulfilled its office is ready to be returned to normal position, and as the lay beats up the spring s3 will maintain the cam-surface ofthe dog in engagement with the actuator or bunter HX -until the lay is fully forward, and then the dog will be freed from the actuator, so that the spring s4 will immediately act to lift the lower end of the dog from the position shown in Fig. L3 sufficiently to clear the actuator on the next Now as the lay moves back the` actuator H will engage the dog i4 and will backward-stroke of the lay, the spring s3 thereafter holding the catcher in normal position, so that the latter moves with the lay .are preferably made resilient, withsuiiicient spring to snap the filling-carrier from between them, as has been described, in-order to-thoroughly clear the discharged filling-carrier from the catcher, said jaws are not necessarily constructed to perform such function,

as in any event the expeller will positively expel the iilling-carrier from the catcher.

It will be obviousV from the foregoing description that the' engagement of an ejected filling-carrier by the catcher acts to move the dog into operative position to coperate with the actuator, and the dog thus forms controlling means operative by or through engagement of the catcher with the filling-carrier to control the operation of the actuator.

My invention is not restricted to the precise construction and arrangement of parts herein shown and described, as the same may be modified or rearranged in various particulars without departing from the spirit and scope of my invention. It will also be obvious that the operation of the catcheris not necessarily restricted to the particular or novel form of transferring mechanism herein shown.
